// The ExportPublicKey method is deprecated:

CkoPublicKey *publickeyObj = [cert ExportPublicKey];
if (cert.LastMethodSuccess == NO) {
    NSLog(@"%@",cert.LastErrorText);
    return;
}

// ...

// ------------------------------------------------------------------------
// Do the equivalent using GetPublicKey.
// Your application creates a new, empty PublicKey object which is passed 
// in the last argument and filled upon success.

CkoPublicKey *publickeyOut = [[CkoPublicKey alloc] init];
BOOL success = [cert GetPublicKey: publickeyOut];
if (success == NO) {
